  • using text and ntext SQL Datatypes in RPG

    - by David Stratton
    I'll preface this with saying that I'm a .NET developer, and am NOT an RPG developer. I'm working with one of our RPG developers to come up with a solution, so any suggestions you provide will get passed to him. We have a scenario where we want our iSeries to read from a SQL Server database. One of the columns is a TEXT column. IN RPG, there is no equivalent data type to use for this. We've gone back and forth on this, and our current plan is to change course, and have our SQL Server write out a text file, which the iSeries can pick up and parse. This is, however, a last resort option, as the data in the file is sensitive, and we'd like to avoid the additional security overhead. We've already got the SQL Server locked down as tight as possible (one user only has read access to this, and that user is an iSeries user.) We don't want to have to worry about transferring files back and forth. However, at this point, we see no other option. We have no in-house Java developers, and need to do this in RPG. So I'm wondering if there are any RPG developers out there who have faced this situation and have any advice.

  • establishing a socket connection from iPhone to MAC/PC

    - by user319572
    Hello, I just started getting into XCode and Co. What I am trying is to send accelerometer data via WLAN to a PC or MAC over a Socket connection. I am trying at the moment with the iPhone simulator, on the other site a netbook with a JAVA program shall receive a test string for starters. Unfortunately my socket will not initialize. What am I doing wrong? NSString *recStr = @"192.168.0.5"; //String with receiver IP NSHost *hoster = [NSHost hostWithName:recStr]; //create a host NSOutputStream *sendData; //create an output stream [NSStream getStreamsToHost:hoster port:8000 inputStream:nil outputStream:&sendData]; [sendData retain]; [sendData setDelegate:self]; [sendData open]; A warning says NSStream may not respond to '+getStreamsToHost:inputSream:outputStream:' So I guess parameters are wrong. But why and how to do it right? The program starts but I don't think I can send anything as long as this warning shows up (have not tried though). Thank you in advance, Andreas

  • Implementing a 2 Legged OAuth Provider

    - by Rob Wilkerson
    I'm trying to find my way around the OAuth spec, its requirements and any implementations I can find and, so far, it really seems like more trouble than its worth because I'm having trouble finding a single resource that pulls it all together. Or maybe it's just that I'm looking for something more specialized than most tutorials. I have a set of existing APIs--some in Java, some in PHP--that I now need to secure and, for a number of reasons, OAuth seems like the right way to go. Unfortunately, my inability to track down the right resources to help me get a provider up and running is challenging that theory. Since most of this will be system-to-system API usage, I'll need to implement a 2-legged provider. With that in mind... Does anyone know of any good tutorials for implementing a 2-legged OAuth provider with PHP? Given that I have securable APIs in 2 languages, do I need to implement a provider in both or is there a way to create the provider as a "front controller" that I can funnel all requests through? When securing PHP services, for example, do I have to secure each API individually by including the requisite provider resources on each? Thanks for your help.

  • Embeddable forum software

    - by Rented
    I am in the planning stages of a specific subject matter community web site, and one feature I feel is required is that of member discussions. However, not in a typical forum style. For example, I don't want the members to have to navigate away from their own "user space" in order to discuss a topic. I think it is best described with an analogous example. Lets say the site is for literature buffs, and each member has a set of pages for keeping notes, progress, questions, etc. on books they are studying/reading. So Joe will have one page for Great Expectations, another for Hamlet, a third for I, Robot, and so forth. Likewise, Jane will have a page for Don Quixote, Lord of the Flies, and also I, Robot. Now, wouldn't it be nice if Joe and Jane could discuss I, Robot from within their own respective pages? Now, at first thought, roll your own seems like the way to go. However, once we start getting into issues such as spam blocking, banning, ratings, pruning, archiving, flooding and so on, well "roll your own" doesn't sound too appealing anymore. Also, I have next to zero experience with forum software. So I'm looking for forum software that has an extensive API or is generally very integration-friendly. I would like to be able to create user groups, topics, permissions, etc. programmatically,as well as the obvious user authentication (most seem open in that respect). The site will most probably be built with Java. Tangler seems like a descent option, but it seems less mature than what I'd prefer.

  • Modular Reduction of Polynomials in NTRUEncrypt

    - by Neville
    Hello everyone. I'm implementing the NTRUEncrypt algorithm, according to an NTRU tutorial, a polynomial f has an inverse g such that f*g=1 mod x, basically the polynomial multiplied by its inverse reduced modulo x gives 1. I get the concept but in an example they provide, a polynomial f = -1 + X + X^2 - X4 + X6 + X9 - X10 which we will represent as the array [-1,1,1,0,-1,0,1,0,0,1,-1] has an inverse g of [1,2,0,2,2,1,0,2,1,2,0], so that when we multiply them and reduce the result modulo 3 we get 1, however when I use the NTRU algorithm for multiplying and reducing them I get -2. Here is my algorithm for multiplying them written in Java: public static int[] PolMulFun(int a[],int b[],int c[],int N,int M) { for(int k=N-1;k>=0;k--) { c[k]=0; int j=k+1; for(int i=N-1;i>=0;i--) { if(j==N) { j=0; } if(a[i]!=0 && b[j]!=0) { c[k]=(c[k]+(a[i]*b[j]))%M; } j=j+1; } } return c; } It basicall taken in polynomial a and multiplies it b, resturns teh result in c, N specifies the degree of the polynomials+1, in teh example above N=11; and M is the reuction modulo, in teh exampel above 3. Why am I getting -2 and not 1?

  • passing timezone from client (GWT) to server (Joda Time)

    - by Caffeine Coma
    I'm using GWT on the client (browser) and Joda Time on the server. I'd like to perform some DB lookups bounded by the day (i.e. 00:00:00 until 23:59:59) that a request comes in, with the time boundaries based on the user's (i.e. browser) timezone. So I have the GWT code do a new java.util.Date() to get the time of the request, and send that to the server. Then I use Joda Time like so: new DateTime(clientDate).toDateMidnight().toDateTime() The trouble of course is that toDateMidnight(), in the absence of a specified TimeZone, will use the system's (i.e. the server's) TimeZone. I've been trying to find a simple way to pass the TimeZone from the browser to the server without much luck. In GWT I can get the GMT offset with: DateTimeFormat.getFormat("Z").fmt(new Date()) which results in something like "-0400". But Joda Time's DateTimeZone.forID() wants strings formatted like "America/New_York", or an integer argument of hours and minutes. Of course I can parse "-0400" into -4 hours and 0 minutes, but I'm wondering if there is not a more straightforward way of doing this.

  • Enterprise SSO & Identity management / recommendations

    - by Maxim Veksler
    Hello Friends, We've discussed SSO before. I would like to re-enhance the conversation with defined requirements, taking into consideration recent new developments. In the past week I've been doing market research looking for answers to the following key issues: The project should should be: Requirements SSO solution for web applications. Integrates into existing developed products. has Policy based password security (Length, Complexity, Duration and co) Security Policy can be managed using a web interface. Customizable user interface (the password prompt and co. screens). Highly available (99.9%) Scalable. Runs on Red Hat Linux. Nice to have Contains user Groups & Roles. Written in Java. Free Software (open source) solution. None of the solutions came up so far are "killer choice" which leads me to think I will be tooling several projects (OWASP, AcegiSecurity + X??) hence this discussion. We are ISV delivering front-end & backend application suite. The frontend is broken into several modules which should act as autonomous unit, from client point of view he uses the "application" - which leads to this discussion regrading SSO. I would appreciate people sharing their experience & ideas regarding the appropriete solutions. Some solutions are interesting CAS Sun OpenSSO Enterprise JBoss Identity IDM JOSSO Tivoli Access Manager for Enterprise Single Sign-On Or more generally speaking this list Thank you, Maxim.

  • Why is C# winforms application not working without VS.NET installed?

    - by Shane
    Hi folks, I have a winforms c# app that has an embedded webbrowser control inside it generated through VS.NET 2008. We sink events by inheriting our events class from HTMLDocumentEvents2. public class IEHTMLDocumentEvents : mshtml.HTMLDocumentEvents2 { public bool onclick(mshtml.IHTMLEventObj pEvtObj) { // Clicking on an input (checkbox, radio, button, image) if (pEvtObj.srcElement.tagName == "INPUT") { // The following will result in a null pointer without VS.NET installed HTMLInputElementClass input = pEvtObj.srcElement as HTMLInputElementClass; } } } The code above works fine when clicking on elements in the webbrowser control on our dev machines with VS.NET installed. However it fails to cast the pEvtObj.srcElement when VS.NET is not installed. This immediately starts working when we install the most basic VS.NET with C# that you can. To note: The rest of the c# app works fine, and you can browser the web through the control fine as well, just that the events like the above 'onclick' can't be handled properly. I thought it would be a DLL version loaded issue but doing a diff of the files loaded indicates only minor differences. 1c1 < Process: C# App without VS.NET installed --- > Process: C# App with VS.NET 2008 installed 18d17 < C:\WINDOWS\assembly\NativeImages_v2.0.50727_32\CustomMarshalers\e148983beeb0f30918b0564849a16456\CustomMarshalers.ni.dll CustomMarshalers.ni.dll Microsoft .NET Framework Custom Marshalers Microsoft Corporation 2.0.50727.3053 36d34 < C:\Documents and Settings\XpHome\Local Settings\History\History.IE5\index.dat index.dat 37a36 > C:\Documents and Settings\XpHome\Local Settings\History\History.IE5\index.dat index.dat 44,45c43,44 < C:\Program Files\<hidden>\<hidden>\Microsoft.mshtml.dll Microsoft.mshtml.dll 7.0.3300.1 < C:\WINDOWS\assembly\NativeImages_v2.0.50727_32\Microsoft.VisualBas#\5b3d048d8c003d743ea5e72caf07773a\Microsoft.VisualBasic.ni.dll Microsoft.VisualBasic.ni.dll Visual Basic Runtime Library Microsoft Corporation 8.0.50727.3053 --- > C:\WINDOWS\assembly\GAC\Microsoft.mshtml\7.0.3300.0__b03f5f7f11d50a3a\Microsoft.mshtml.dll Microsoft.mshtml.dll 7.0.3300.1 > C:\WINDOWS\assembly\GAC_MSIL\Microsoft.VisualBasic\8.0.0.0__b03f5f7f11d50a3a\Microsoft.VisualBasic.dll Microsoft.VisualBasic.dll Visual Basic Runtime Library Microsoft Corporation 8.0.50727.3053 50,52c49,51 < c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\mscorjit.dll mscorjit.dll Microsoft .NET Runtime Just-In-Time Compiler Microsoft Corporation 2.0.50727.3053 < C:\WINDOWS\assembly\NativeImages_v2.0.50727_32\mscorlib\9adb89fa22fd5b4ce433b5aca7fb1b07\mscorlib.ni.dll mscorlib.ni.dll Microsoft Common Language Runtime Class Library Microsoft Corporation 2.0.50727.3053 < c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\mscorwks.dll mscorwks.dll Microsoft .NET Runtime Common Language Runtime - WorkStation Microsoft Corporation 2.0.50727.3053 --- > c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\mscorjit.dll mscorjit.dll Microsoft .NET Runtime Just-In-Time Compiler Microsoft Corporation 2.0.50727.3082 > C:\WINDOWS\assembly\NativeImages_v2.0.50727_32\mscorlib\7124a40b9998f7b63c86bd1a2125ce26\mscorlib.ni.dll mscorlib.ni.dll Microsoft Common Language Runtime Class Library Microsoft Corporation 2.0.50727.3603 > c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\mscorwks.dll mscorwks.dll Microsoft .NET Runtime Common Language Runtime - WorkStation Microsoft Corporation 2.0.50727.3603 94,98c93,97 < C:\WINDOWS\assembly\NativeImages_v2.0.50727_32\System.Configuration\cb4cb21d14767292e079366a5d3d76cd\System.Configuration.ni.dll System.Configuration.ni.dll System.Configuration.dll Microsoft Corporation 2.0.50727.3053 < C:\WINDOWS\assembly\NativeImages_v2.0.50727_32\System.Drawing\6978f2e90f13bc720d57fa6895c911e2\System.Drawing.ni.dll System.Drawing.ni.dll .NET Framework Microsoft Corporation 2.0.50727.3053 < C:\WINDOWS\assembly\NativeImages_v2.0.50727_32\System\aa7926460a336408c8041330ad90929d\System.ni.dll System.ni.dll .NET Framework Microsoft Corporation 2.0.50727.3053 < C:\WINDOWS\assembly\NativeImages_v2.0.50727_32\System.Windows.Forms\9a254c455892c02355ab0ab0f0727c5b\System.Windows.Forms.ni.dll System.Windows.Forms.ni.dll .NET Framework Microsoft Corporation 2.0.50727.3053 < C:\WINDOWS\assembly\NativeImages_v2.0.50727_32\System.Xml\36f3953f24d4f0b767bf172331ad6f3e\System.Xml.ni.dll System.Xml.ni.dll .NET Framework Microsoft Corporation 2.0.50727.3053 --- > C:\WINDOWS\assembly\GAC_MSIL\System.Configuration\2.0.0.0__b03f5f7f11d50a3a\System.Configuration.dll System.Configuration.dll System.Configuration.dll Microsoft Corporation 2.0.50727.3053 > C:\WINDOWS\assembly\NativeImages_v2.0.50727_32\System.Drawing\abb2ac7e08bee026f857d8fa36f9fe6f\System.Drawing.ni.dll System.Drawing.ni.dll .NET Framework Microsoft Corporation 2.0.50727.3053 > C:\WINDOWS\assembly\NativeImages_v2.0.50727_32\System\3de5bd01124463d7862bd173af90bc83\System.ni.dll System.ni.dll .NET Framework Microsoft Corporation 2.0.50727.3053 > C:\WINDOWS\assembly\NativeImages_v2.0.50727_32\System.Windows.Forms\d2ea8d76f015817db1607075812b555f\System.Windows.Forms.ni.dll System.Windows.Forms.ni.dll .NET Framework Microsoft Corporation 2.0.50727.3053 > C:\WINDOWS\assembly\NativeImages_v2.0.50727_32\System.Xml\5913d3f81e77194ec833991b1047a532\System.Xml.ni.dll System.Xml.ni.dll .NET Framework Microsoft Corporation 2.0.50727.3082

  • What is the worst programming language you ever worked with? [closed]

    - by Ludwig Weinzierl
    If you have an interesting story to share, please post an answer, but do not abuse this question for bashing a language. We are programmers, and our primary tool is the programming language we use. While there is a lot of discussion about the best one, I'd like to hear your stories about the worst programming languages you ever worked with and I'd like to know exactly what annoyed you. I'd like to collect this stories partly to avoid common pitfalls while designing a language (especially a DSL) and partly to avoid quirky languages in the future in general. This question is not subjective. If a language supports only single character identifiers (see my own answer) this is bad in a non-debatable way. EDIT Some people have raised concerns that this question attracts trolls. Wading through all your answers made one thing clear. The large majority of answers is appropriate, useful and well written. UPDATE 2009-07-01 19:15 GMT The language overview is now complete, covering 103 different languages from 102 answers. I decided to be lax about what counts as a programming language and included anything reasonable. Thank you David for your comments on this. Here are all programming languages covered so far (alphabetical order, linked with answer, new entries in bold): ABAP, all 20th century languages, all drag and drop languages, all proprietary languages, APF, APL (1), AS400, Authorware, Autohotkey, BancaStar, BASIC, Bourne Shell, Brainfuck, C++, Centura Team Developer, Cobol (1), Cold Fusion, Coldfusion, CRM114, Crystal Syntax, CSS, Dataflex 2.3, DB/c DX, dbase II, DCL, Delphi IDE, Doors DXL, DOS batch (1), Excel Macro language, FileMaker, FOCUS, Forth, FORTRAN, FORTRAN 77, HTML, Illustra web blade, Informix 4th Generation Language, Informix Universal Server web blade, INTERCAL, Java, JavaScript (1), JCL (1), karol, LabTalk, Labview, Lingo, LISP, Logo, LOLCODE, LotusScript, m4, Magic II, Makefiles, MapBasic, MaxScript, Meditech Magic, MEL, mIRC Script, MS Access, MUMPS, Oberon, object extensions to C, Objective-C, OPS5, Oz, Perl (1), PHP, PL/SQL, PowerDynamo, PROGRESS 4GL, prova, PS-FOCUS, Python, Regular Expressions, RPG, RPG II, Scheme, ScriptMaker, sendmail.conf, Smalltalk, Smalltalk , SNOBOL, SpeedScript, Sybase PowerBuilder, Symbian C++, System RPL, TCL, TECO, The Visual Software Environment, Tiny praat, TransCAD, troff, uBasic, VB6 (1), VBScript (1), VDF4, Vimscript, Visual Basic (1), Visual C++, Visual Foxpro, VSE, Webspeed, XSLT The answers covering 80386 assembler, VB6 and VBScript have been removed.

  • REST tools support for development and testing

    - by nzpcmad
    There is a similar question here but it only covers some of the issues below. We have a client who requires web services using REST. We have tons of experience using SOAP and over time have gathered together a really good set of tools for SOAP development and testing e.g. soapUI Eclipse plugins wsdl2java WSStudio By "tools" I mean a product "out of the box" that we can start using. I'm not talking about cutting code to "roll our own" using Ajax or whatever. The tool set for REST doesn't seem to be nearly as mature? What tools are out there (we use C# and Java mainly) ? Do the tools handle GET, POST, PUT, and DELETE? Is there a decent Eclipse plugin? Is there a decent client testing application like WSStudio where you point the tool to the WSDL and it generates a proxy on the fly with the appropriate methods and inputs and you simple type the data in? Are there any good package monitoring tools that allow you to look at the data? (I'm not thinking about sniffers like Wireshark here but rather things like soapUI that allow you to see the request / response) ?

  • Why are floating point values so prolific?

    - by Kibbee
    So, title says it all. Why are floating point values so prolific in computer programming. Due to problems like rounding errors, and not being able to even accurately represent numbers such as 0.1, I really can't see how they got as far as they did. I understand that the computation is faster with floating point numbers, however, I can think of only a few cases that they actually the right data type would be using. If you sat back and think about every time you used a floating point value, how many times did you say, well, some error would be ok, as long as the result was a few microseconds faster. It really makes me think because Jeff was talking about NP completeness, and how heuristics give an answer that is kind of right. And well, computers shouldn't do that. They should give you the answer that is correct. Yet we see floating point values used in many applications where they are completely not valid. What really bugs me, isn't that floating point exists, but that in many languages, there isn't even a viable alternative, non-floating point, decimal value. A lot of programmers when doing financial applications have to fall back to storing the number of cents in an integer field. Which brings with it all kinds of other problems. Why do floats continue to be so prolific, even though they can't represent the real answer, and we expect computers to be accurate? [EDIT] Just to clarify, I was talking about Base 2 floating points, and not base 10 floating points. .Net offers the Decimal data type, which is a base 10 floating point value which offers a much better representation of the numbers we deal with on a daily basis in most computer programs. I find it hard to believe that even modern languages like Java don't support base 10 floating point values, unless you want to move into the realm of things like BigDecimal, which isn't really the right answer either in a lot of situations.

  • image/jpeg returned by groovy/grails is OK on development system, but corrupt on prod system. What c

    - by ?????
    I have a groovy/grails application that needs to serve images It works fine on my dev box, the image is returned properly. Here's the start of the returned JPEG, as seen by od -cx 0000000 377 330 377 340 \0 020 J F I F \0 001 001 001 001 , d8ff e0ff 1000 464a 4649 0100 0101 2c01 but on the production box, there's some garbage in front, and the d8ff e0ff before the 1000 is missing 0000000 ? ** ** ? ** ** ? ** ** ? ** ** \0 020 J F bfef efbd bdbf bfef efbd bdbf 1000 464a 0000020 I F \0 001 001 001 \0 H \0 H \0 \0 ? ** ** ? 4649 0100 0101 4800 4800 0000 bfef efbd It's the exact same code. I just moved the .war over and run it on a different machine. (Isn't Java supposed to be write once, run everywhere?) Any ideas? An "encoding" problem? The code is sent to the response like this: response.contentType = "image/jpeg"; response.outputStream << out;

  • ASP.NET MVC - Parent-Child Table Relation - how to creat Children in MVC (example request)

    - by adudley
    Hi All. In a standard setup of Parent Child relation, lets say Project and Task. Where a Project is made up of lots of Tasks. So in a standard RDB, we have a Project (ID, Name, Deadline) Task (ID, FK_To_Project, Name, Description, isCompleted) this is all very straight forward. We have an MVC View that views Projects, so we get a nice list of all the project Names next to each deadline. Now we want to CREATE a new PROJECT. The Edit view opens, we type a name, say, 'Make a cup of Tea', with tomorrow as the deadline! Still in this view/web page, I would like a list of all the Child Tasks, in a standard list, with Edit, Delete, and a Create/Add Task button too, just below the 'parent table' details. The simplest way to describe this, is the Parents Table Create/Edit view, with the Childes List View Below it. 1) The ideal solution will also allow my Child Table (Tasks) to have Children also (for more complex scenarios) , and so on, and on, and on. 2) If I navigate away from my Created Project, I don’t want all sorts of random stuff laying around, they went away, it’s gone! 3) I’d expect all the same functionality when Editing an existing project. I’m struggling with the ‘Add New Child’, I had a model dialog (jquery) and all was well, but now when editing an existing child/task, I need to populate the Child Edit, which is a pain and will need loads of java script I think :( How can this be achieved in MVC, does anybody have any examples?

  • GWT UiBinder doesn't load the stylesheet

    - by halish
    I wanted to make a GWT widget using UiBinder. So I made: UserPanel.ui.xml like this: <?xml version="1.0" encoding="UTF-8"?> <ui:UiBinder xmlns:ui='urn:ui:com.google.gwt.uibinder' xmlns:g='urn:import:com.google.gwt.user.client.ui'> <ui:with field="res" type="com.example.resources.UserPanelResources" /> <g:VerticalPanel styleNames='{res.userpanel.main}'> ...some other widgets go here... </g:VerticalPanel> </ui:UiBinder> UserPanel.css like this: .main { width: 1000px; background-color: #f9f9fa; padding: 15px 10px; font-family: "Georgia"; } and UserPanelResources.java like: public interface UserPanelResources extends ClientBundle { public interface UserPanelCss extends CssResource { String main(); } @Source("css/userpanel.css") UserPanelCss userpanel(); } All the files and packages are in their place, as everything compiles just fine. But when I run the Development Mode, the styles are not applied! I tried many different approaches, but it still doesn't work. What I noticed, is that in the HTML, the VerticalPanel is given the class name obfuscated by GWT, but the CSS is not send to the browser - in fact, the GWT doesn't even ask for it. Am I missing something?

  • Generating scala AST for recursive method.

    - by scout
    I am generating the scala AST using the following code: val setting = new Settings(error) val reporter = new ConsoleReporter(setting, in, out) { override def displayPrompt = () } val compiler = new Global(setting, reporter) with ASTExtractor{ override def onlyPresentation = true } //setting.PhasesSetting("parser", "parserPhase") val run = new compiler.Run val sourceFiles:List[String] = List("Test.scala") run.compile(sourceFiles.toList) I guess this is the standard code used to run the compiler in the code and generate the AST to work with. The above code worked fine for any valid scala code in Test.scala till now. When I use a recursive function in Test.scala, like def xMethod(x:Int):Int = if(x == 0) -1 else xMethod(x-1) It gives me a java.lang.NullPointerException. The top few lines of the stack trace look like this at scala.tools.nsc.typechecker.Typers$Typer.checkNoDoubleDefsAndAddSynthetics$1(Typers.scala:2170) at scala.tools.nsc.typechecker.Typers$Typer.typedStats(Typers.scala:2196) at scala.tools.nsc.typechecker.Typers$Typer.typedBlock(Typers.scala:1951) at scala.tools.nsc.typechecker.Typers$Typer.typed1(Typers.scala:3815) at scala.tools.nsc.typechecker.Typers$Typer.typed(Typers.scala:4124) at scala.tools.nsc.typechecker.Typers$Typer.typed(Typers.scala:4177) at scala.tools.nsc.transform.TailCalls$TailCallElimination.transform(TailCalls.scala:199) The code works fine for a method like def aMethod(c:Int):Int = { bMethod(c) } def bMethod(x:Int):Int = aMethod(x) Please let me know if recursive functions need any other setting.

  • Finding JNP port in JBoss from Servlet

    - by Steve Jackson
    I have a servlet running in JBoss (4.2.2.GA and 4.3-eap) that needs to connect to an EJB to do work. In general this code works fine to get the Context to connect and make RMI calls (all in the same server). public class ContextFactory { public static final int DEFAULT_JNDI_PORT = 1099; public static final String DEFAULT_CONTEXT_FACTORY_CLASS = "org.jnp.interfaces.NamingContextFactory"; public static final String DEFAULT_URL_PREFIXES = "org.jboss.naming:org.jnp.interfaces"; public Context createContext(String serverAddress) { //combine provider name and port String providerUrl = serverAddress + ":" + DEFAULT_JNDI_PORT; //Set properties needed for Context: factory, provider, and package prefixes. Hashtable<String, String> env = new Hashtable<String, String>(3); env.put(Context.INITIAL_CONTEXT_FACTORY, DEFAULT_CONTEXT_FACTORY_CLASS); env.put(Context.PROVIDER_URL, providerUrl); env.put(Context.URL_PKG_PREFIXES, DEFAULT_URL_PREFIXES); return new InitialContext(env); } Now, when I change the JNDI bind port from 1099 in server/conf/jboss-service.xml I can't figure out how to programatically find the correct port for the providerUrl above. I've dumped System.getProperties() and System.getEnv() and it doesn't appear there. I'm pretty sure I can set it in server/conf/jndi.properties as well, but I was hoping to avoid another magic config file. I've tried the HttpNamingContextFactory but that fails "java.net.ProtocolException: Server redirected too many times (20)" env.put(Context.INITIAL_CONTEXT_FACTORY, "org.jboss.naming.HttpNamingContextFactory"); env.put(Context.PROVIDER_URL, "http://" + serverAddress + ":8080/invoker/JNDIFactory"); Any ideas?

  • Date query with Hibernate on Timestamp Column in PostgreSQL

    - by Shashikant Kore
    A table has timestamp column. A sample value in that could be 2010-03-30 13:42:42. With Hibernate, I am doing a range query Restrictions.between("column-name", fromDate, toDate). The Hibernate mapping for this column is as follows. <property name="orderTimestamp" column="order_timestamp" type="java.util.Date" /> Let's say, I want to find out all the records that have the date 30th March 2010 and 31st March 2010. A range query on this field is done as follows. Date fromDate = new SimpleDateFormat("yyyy-MM-dd").parse("2010-03-30"); Date toDate = new SimpleDateFormat("yyyy-MM-dd").parse("2008-03-31"); Expression.between("orderTimestamp", fromDate, toDate); This doesn't work. The query is converted to respective timestamps as "2010-03-30 00:00:00" and "2010-03-31 00:00:00". So, all the records for the 31st March 2010 are ignored. A simple solution to this problem could be to have the end date as "2010-03-31 23:59:59." But, I would like to know if there is way to match only the date part of the timestamp column. Also, is Expression.between() inclusive of both limits? Documentation doesn't throw any light on this.

  • Japanese text garbled while passing to a http restlet service

    - by satish-gunuputi
    Hi , I have a perl client which is calling a http restlet service (put method). Some of the parameters in this call contain japanese text. when I printed the contents of these request parameters in the restlet service I found these chars garbled ! This is my PERL client code: my %request_headers = ( 'DocumentName' => $document_name, --> This name is a JAPANESE String 'DocumentDescription' => 'Test Japanese Chars', 'content-length' => 200, 'Content-Type' => 'application/octet-stream; charset=utf-8', 'User-Agent' => "JPCharTester", ); $s-write_request('PUT', '/test-document/TEST/TEST_DOCUMENT' , %request_headers, $content); in this call both the values of $context and $document_name are JAPANESE Strings. But ONLY the document_name is received as garbled in my backend service. Here goes the Service code: String URL_ENCODING = "UTF-8"; String documentName = requestHeaders.getFirstValue("DocumentName"); System.out.println("Encoded Document Name : "+documentName+" <<<"); --> documentName is garbled here try { documentName = URLDecoder.decode(documentName, URL_ENCODING); System.out.println(>>> Decoded Document Name : "+documentName+" <<<"); --> documentName is garbled here } catch (java.io.UnsupportedEncodingException ex) { throwException(ex.getMessage(), Status.SERVER_ERROR_INTERNAL, ex); } both the above log statements printed GARBLED TEXT !! Can someone tell me what is the mistake I am doing and how to fix this ? Thanks in advance for your help. Regards, Satish.

  • How to configure hbm2java and hbm2dao to add packagename to generated classes

    - by mmm
    Hi, I'm trying to configure hbm2java with maven to generate POJO classes and DAO objects. One of the issues I'm dealing with is package names aren't generated. I'm using the following pom for that: <execution> <id>hbm2java</id> <phase>generate-sources</phase> <goals> <goal>hbm2java</goal> </goals> <inherited>false</inherited> <configuration> <components> <component> <name>hbm2java</name> <implementation>configuration</implementation> </component> </components> <componentProperties> <packagename>package.name</packagename> <configurationfile>target/hibernate3/generated-mappings/hibernane.cfg.xml</configurationfile> </componentProperties> </configuration> </execution> Yet the generated code begins with the following: // default package // Generated 2010-05-17 13:11:51 by Hibernate Tools 3.2.2.GA /** * Messages generated by hbm2java */ public class Messages implements java.io.Serializable { Is there a way to force maven to generate the package part as defined in packagename?
